Abstract: 349,723. Mixing - machines. WITHERS, J. S., 51, Chancery Lane, London.-(Koehring Co.; 31st Street, Milwaukee, Wisconsin, U.S.A.) April 14, 1930, No. 11821. [Class 86.] A concrete mixing machine, which works continuously, comprises means, driven from the machine, for controlling the mixing period and operating the charging and discharging devices. The drum 16, Fig. 1, is driven by a shaft 33 on which is a clutchcontrolled drum 35 for hoisting the charging-skip 28, the drum being discharged bv a tiltable shoot 53 which is rocked by a crossed belt driven alternately in opposite directions from a cross shaft driven from the shaft 25 through bevel gearing 62, 63 the gears 63 being clutched to the shaft 25 by a clutch 64 controlled by a lever 70. The lever 70 is engaged by pins 71, 72 so as to throw the clutch out when the shoot 53 reaches its limiting positions, and is connected with a lever 87 on the timing mechanism. The winding drum clutch, with which is combined a brake, is operated by a lever 39 interconnected with a throw-out member 67 operated by the charging- skip 28 in its upper position, and with a lever 77 on the timing-device. As shown in Fig. 11, the lever 87 is interconnected with a lever 85 and both are provided with pivoted spring dogs 84, 86 engaged by projections 82, 83 on a disc 80 carried by a shaft 92 ; the lever 77 is fitted with a similar dog engaged by a projection 75. Rotation of the shaft 92 in one direction effects the operation of the levers 77, 85, 87 to actuate the winding-gear and discharge shoot; on the reverse rotation the dogs move about their pivots idly. The shaft 92, Fig. 9, is connected with a clutch member 97 adapted to be moved into engagement with a clutch member 96 mounted on a worm wheel 98 driven by a worm 99 on a shaft 100 driven continuously by chain gearing from the shaft 25. The movable clutch member 97 is thrown into operation by the engagement of a projection 105 with a fixed pin 104. The shaft 92 is then rotated till the projection 105 engages an adjustable pin 107 which disengages the clutch member 97; the shaft 92 and clutch member 97 are then rotated back to their original position by a coiled spring 109 to start a new cycle. The pin 107 is carried by a sleeve 94 which can be turned on its shaft to adjust the radial position of the pin and so vary the mixing period; the sleeve 94 is provided with an arm 112 by means of which the pin 107 is set.

Title: Manufacture of sheets from polymerisation products
IPC: C08L27/00
Filed: 1934-04-27
Abstract: Sheets, films, and foils are obtained by spreading a homogeneous aqueous suspension of a synthetic polymerization product which is thermoplastic and does not harden under the influence of heat and pressure, on a support, evaporating the water and heating the layer of powdered polymerization product under a high pressure and at a temperature above the softening point of the product.  The suspension may contain a dyestuff, pigment, filler, or softening agent.  It may consist of an emulsion formed in the production of the polymerized product or it may be obtained from such emulsion by concentration, by evaporation or addition of powdered product, or by treatment to increase the viscosity.  For the heat and pressure treatment the dried layer may be placed between polished metal plates.  In an example, a polymerized mixture of vinyl chloride and methyl acrylate is dispersed with water in a colloid mill.  The suspension is poured or sprayed to form a uniform layer on a metal plate and dried in stages.  The dried mass is transformed into a sheet by subjection to heat and pressure.  Other examples describe the production of sheets from aqueous emulsions or pastes of polyvinyl chloride and butyl phthalate, of chlorinated polyvinyl chloride, tripropyl phosphate and red iron oxide, and of a mixed polymerized product of vinyl chloride and methyl acrylate with zinc white.  The sheets may be used in making laminated glass, windows for motor cars, aeroplanes, tents, and gas masks.

Abstract: 528,514. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., and WAGSTAFFE, C. F. A. April 28, 1939, No. 12786. Class 40 (v)] The crossed aerials of a directive system of the Adcock type are so connected together that the current fed to a cathode-ray or other direct-reading indicator is the vector sum of the signals received by all four of the aerials, so as to give a substantially circular or non-directional response. Or the vector difference of one pair may be combined with the vector difference of the second pair to give a figure-of-eight response, whilst a third component represents the vector sum from all four aerials, and corresponds to a signal which would be obtained from a fifth aerial located at the centre of the square, in order to give a " sense " indication. As shown in Figs. 1 and 2, the input windings Wll, W41 and W32, W21 feed signals from the corresponding pairs of aerials 1, 3 and 2, 4 respectively, to secondary windings W12, W32 and W22, W42 which supply difference components in each case, to an indicator connected across the terminals O1. At the same time, the tertiary windings W13, W23, W33 and W43 feed the vector sum of all four aerials to the terminals 02. The directional and non-directional currents from O1 and 02 respectively are fed to an indicator to give both the direction and sense of a distant transmitter. The transformer couplings may be replaced by centre-tapped series windings, or by other equivalent impedances. The system may be used for transmission.
